Open Source Video Upscaler
Upscaling a video means shipping the footage somewhere to be enhanced, and that footage is often exactly what you'd least want sitting on someone else's GPU - unreleased cuts, personal archives, private clips - while a cloud service meters you per minute on top of it. The open source tools here run the AI and algorithmic enhancement on your own machine, so the source never leaves the room and the only ceiling on how much you process is your own hardware.
